I have the following code:

```julia
mutable struct KiteObserver
    length::Vector{Float64}
    elevation::Vector{Float64}
end
function KiteObserver()
    KiteObserver(Float64[], Float64[])
end

```

I get the warning:

```julia
Possible method call error.Julia(IncorrectCallArgs)
Float64(x [, mode::RoundingMode])

```

Any idea why? Is it a bug? Is there a workaround?

Hello,  
I cannot recreate this warning. Can it be something with the Julia version? The version I am using is 1.10.2.

I also have problems to replicate with an MWE. It happens in this code:

I checked it on two computers, so it is not a problem with my specific VSCode installation.

I also have some wrong warnings like that. I think I have at some point disabled the method call warnings (not sure how). It is a bug, certainly. Sometimes hard to reproduce.
